Common questions about this tool
Paste your text into the tool and specify the desired line width (number of characters). The tool automatically wraps lines at word boundaries, preserving readability while ensuring no line exceeds your specified width.
Yes, the tool offers options to wrap at character boundaries for code or when word boundaries aren't appropriate. This breaks lines exactly at the specified width, even if it splits words.
Yes, the tool can preserve existing indentation when wrapping. Indented lines maintain their indentation, and wrapped continuation lines can be indented to match or use hanging indents for better readability.
Set the line width to 72-78 characters (standard email width), enable word boundary wrapping, and the tool formats your text for email readability. This prevents long lines that break email formatting.
Yes, the tool is perfect for wrapping code comments and documentation. It preserves code structure while wrapping comment text, making code more readable and maintaining consistent formatting standards.

Learn what this tool does, when to use it, and how it fits into your workflow.
This tool wraps long text into lines of a chosen width. You paste or type your text into a single input area, choose a wrap width in characters, and the tool rewrites the text so that each line fits within that width. It can try to break at word boundaries or break exactly at the character limit. You can also upload a text file and download the wrapped result.
The problem it solves is formatting text for contexts where very long lines are hard to read or do not fit. Email clients, code comments, terminal windows, and many document formats work better when lines have a consistent and moderate length. Manually inserting or moving line breaks is tedious and error-prone. This tool automates the wrapping based on clear rules and keeps the text easy to read.
The text wrap tool is useful for writers preparing email content, developers formatting comments or documentation, and anyone who needs to fit text into narrow columns. It is simple enough for a first-time user yet offers enough control to satisfy technical users who care about word boundaries and line markers.
Text wrapping is the process of splitting a long line of text into multiple shorter lines so that none of them exceed a given width. The width is often measured in characters when working with monospaced fonts or plain text formats. Wrapping can happen at word boundaries, where whole words are kept on one line if possible, or at exact character positions, where lines are cut regardless of where words fall. A related operation involves removing line breaks as part of a similar workflow.
When you wrap at word boundaries, you ensure that lines end between words whenever possible. This makes the text easier to read and avoids splitting words across lines. However, if you encounter a very long word that is longer than the chosen width, a simple word-based method must still break somewhere inside that word to avoid a line exceeding the limit.
People often face wrapping issues when copying text between applications, sending plain text emails, or adding comments in code. Without a clear tool, they might count characters manually or rely on the editor’s auto-wrap settings, which may not match the desired standard width. This text wrap tool uses a deterministic algorithm to break lines and lets you control the width, whether to preserve words, and whether to show markers for wrapped lines, so the behavior is predictable and repeatable.
Preparing text for email. Many plain-text emails follow a standard line width, often around 72–78 characters, to prevent wrapping issues in different clients. You paste your message into the tool, set the wrap width to your desired value, keep word preservation on, and copy the result into your email client. The lines are now consistent and easy to read. For adjacent tasks, trimming whitespace addresses a complementary step.
Wrapping code comments. Code guidelines often suggest keeping comments within a fixed column limit. You paste a long comment block or documentation excerpt into the tool, choose the typical width (for example, 80), and enable word preservation so that it breaks at spaces. The resulting wrapped text fits neatly into code and respects existing indentation when you paste it back into your editor.
Formatting text for narrow columns. If you are preparing content for display in a narrow column or console window, you set the wrap width to match the column width. The preview with the ruler helps you confirm that no line is longer than the column, and the markers show where each wrapped line ends.
Cleaning up logs for readability. Long log lines can be hard to read and scroll through. By pasting them into the tool and using a moderate wrap width, you can reformat them into more readable chunks, especially if you do not mind words being split at fixed widths for data-like content. When working with related formats, reversing text can be a useful part of the process.
The core wrapping function starts by validating inputs. If the text is empty or not a string, it returns an empty string. If the width is not a positive number, it returns the original text unchanged. It then clamps the width to a safe range, ensuring it is at least one and not more than a preset upper limit, and floors it to an integer.
The function splits the input into lines using newline characters. It processes each line separately so that existing paragraph breaks are preserved. For each line, if the length is already within the width, it is added to the result unchanged. If the line is longer, a loop breaks it into segments.
Inside the loop, a provisional break index is set at the width. When word preservation is enabled, the function searches for the last space character at or before that index. If found and not at the very start, it uses that position as the break index so that the line break is placed between words. If no space is found—for example, in a long word that exceeds the width—the break index remains at the width, causing a hard break inside the word. In some workflows, adding line numbers is a relevant follow-up operation.
The function then takes the substring from the start of the remaining text up to the break index, trims any trailing spaces, and appends it as one wrapped line. It trims leading spaces from the remainder and continues looping until the remainder fits within the width or is empty. A safety check ensures that if no progress is made between iterations (which might indicate unexpected content), it forces a simple cut at the safe width to avoid infinite loops.
Once all lines have been processed, the function joins the wrapped lines with newline characters to produce the final wrapped text. The wrapping process is deterministic for a given input, width, and preserveWords setting.
The Smart Optimize function is separate. It requires non-empty text and a positive width. It sends both to a backend service that can return either a plain optimized string or an object containing an "optimizedText" property. The tool validates the response and either uses the optimized content or falls back to the original text if the response is invalid. Any errors in this process are logged and rethrown with a clear message. For related processing needs, sorting lines alphabetically handles a complementary task.
| Limit or option | Value |
|---|---|
| Maximum input length | 50,000 characters |
| Maximum file size per upload | 5 MB |
| Wrap width range | 20 to 200 characters in the UI (internally clamped further for safety) |
| Supported file types | Plain text-like files (e.g., .txt, .md, .log) and text MIME types |
Staying within these limits helps the tool remain responsive and ensures that wrapping is accurate and fast.
Use word preservation for natural language text such as emails, articles, and documentation. This keeps sentences readable and avoids splitting words awkwardly across lines. For data-like strings or long identifiers where words are not important, you may prefer strict character wrapping.
When wrapping code comments or documentation within code, consider your project’s style guide. Choose a width that matches your editor or linter settings to avoid reflow by other tools.
Be aware that the tool does not attempt to understand or preserve special leading characters such as comment markers or bullet symbols. If you need those preserved at the start of each wrapped line, you may need to adjust the result manually or pre-process the text.
If the Smart Optimize feature fails or returns unexpected results, use the regular wrapping mode alone. The core wrapping logic does not depend on the optimization engine and will still format your text correctly.
For very long or complex texts, test the wrapped output in the final environment (such as an email client or code editor) to confirm that it appears as expected. Different fonts and display widths can change perceived line lengths even when the character count is correct.
We’ll add articles and guides here soon. Check back for tips and best practices.
